(Summary)The Climate Change Geoscience Program (CCG) was a five year science program conducted between 2006-2011 at the Earth Science Sector (ESS) within Natural Resources Canada (NRCan). The
objective of the program was to provide critical earth science information that would support policy and regulation decisions on adapting to environmental impacts from climate change. The program's success was based on the development of a scientific
knowledge base and the integration of this knowledge into policy decisions that would mitigate any risk of climate change on the welfare of Canadians. The program's basic role lies in providing a base of geoscience knowledge, accomplished by
identifying the knowledge needs and gaps through collaboration with stakeholders. Specifically the geoscience in the CCG Program focused on those environmental variables that will be most impacted and altered by a changing climate namely: 1) the
cryosphere (permafrost, glaciers and snow cover), 2) water (availability trends and impacts as well as water level changes) and 3) vulnerable landscapes (particularly coastal areas and northern ecosystems). The knowledge base is being
delivered through a mix of earth observation, both remote and in-situ, and quantitative assessments of landscape and ecosystem response. This includes looking at the past and present in order to increase our certainty in making decisions for the
future. The scientific accomplishments as presented in this document have been well recognized in advancing the scientific knowledge base on climate change science. These include recognition by scientific groups such as the Intergovernmental Panel on
Climate Change, National Round Table on the Environment and the Economics and contributing towards a Noble Prize for outstanding achievements. The list of publications is presented as a separate document and includes over 150 articles. (ADD some more
detail). The scientific findings have and will continue to provide the necessary understanding to ensure that we will be better able to adapt to changes in our environment resulting from a changing climate. In all cases partnerships with user
communities were fundamental to ensure that knowledge was relevant and would be ultimately used in decision making. This was achieved by working directly with stakeholders from key economic and natural resource sectors, communities, scientific and
professional institutions, governments and industry, within an integrated risk assessment framework. The user community has been appreciative of the program's contribution including the acknowledgement by Daniel Shewchuk, Minister of Environment for
Nunavut on the contribution of the Northern Collaborative on Climate Change to the development of "… the best climate change adaptation plan in Canada. " Northern vulnerability was particularly highlighted in the program, responding to the
federal government's Northern Strategy vision. The strategy notes the heightened need for climate change in the North and results from the CCG Program will set the stage for continued scientific contributions on adapting to climate change in
Canada's North. Partnerships that were forged provide an opportunity to collaborate on future activities. This final report highlights the success of the Program and illustrates the scientific accomplishments of dedicated scientists. As a result
the Program has accomplished the difficult task of undertaking and completing a variety of scientific activities on climate change that have and will continue to benefit Canadians by providing information that will guide decisions on adapting to
climate change. As a final point a special acknowledgement is extended to Dr. Phil Hill who was the initial Program Manager and set the framework and spirit for the program.
